HENRY A. RIEMANN, OE HANNIBAL, MISSOURI.

CONCRETE-PILE-MAKING MACHINE.

To all whom it may concern.

Be it known that I, HENRY A. RIEMANN, a citizen of the United States, residing at Hannibal, in the county of Marion and State of Missouri, have invented certain new and useful Improvements in Concrete-Pile-Making Machines, of which the following is a specification. I

This invention has relation to certain new and useful improvements in concrete pile f making machines. My invention has for its primary ob ect the provision of an improved machine which will operate in an eflicient manner to roll a wire fabric covered with a concrete layer, and reinforced by a plurality of primary securing wires and a plurality of lengthwise positioned metal reinforcing rods.

A further object is to provide a machine including the combination of certain mechanical instrumentalities by means of which cylindricahor tapered pointed piles may be made in an efiicient manner having finished outer surfaces and reinforced by means of a plurality of primary supporting wires and embedded convolutely formed wire fabric reinforced by means of suitable lengthwise positioned strengthening rods.

WVith the above and other objects in view the present invention consists in the combi nation and arrangement of parts as will be hereinafter more fully described and particularly pointed out in the appended claims, it being understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings forming a part of this specification, and in which like numerals of reference indicate similar parts-in the several views, Figure 1 shows a side elevational view of a machine embodying my invention. Fig. 2 shows an end view thereof with a fragmentary portion of the car. Fig. 3 shows an end view of the car with its fragmentary portion of the winding shaft. Fig. 4 shows a top view.

Referring to the drawings, the frame of the machine comprises the longitudinal base sills 1, extending between the ends of which are transversely arranged sills 2. Extend: ing vertically from each end of each of sills 1 is an upright member 3 and at a suitabl di an m th e uprights, h n

the uprights 3 and 4, respectively, are the similar spacing bars 7 and 7 on which are mounted,on their opposite ends the adjusting jacks 8 and 8. These jaclrs have the screw bars 9 and 9 which supportthe adjustable transverse bars 10 and 10, said bars being vertically adjustable by means of the bolts 22 arranged in the bars and passing through the vertically arranged elongated slots 23 in the said uprights. Mounted on the upper face of the bars 10 and 10 are the journal bearing boxes ll, 11, and 13, while extending from the lower face of these bars are the similar boxes 12 and 12. Extending through the boxes 11 and 11, and at either end of the frame between the uprights 3 and 4 is a shaft 20, having thereon a tically a journal box 30. This box is divided Patented June 18, 1912.

intotwoparts, so as to permit the insertion of the p voted journal bearing 33, which is adapted to swing on the trunnions 32 engaged in suitable recesses in the box 30. The box is provided with the guide flanges 31,- which engage the vertical members 27. Formed on the upper side of the box 30 is the eye member 34, to which is attached one end of a rope or other suitable cable 49, which passes over the pulley 50 mounted in the bearings 51 on the cross bar 5, the opposite end of the rope being wound on the drum 47. Thus when the drum 47 is rotated in one direction the rope 49 will be wound thereon to draw the box30 upwardly.

. 7 3 onwhich is mounted ing mounted in the ends of the portions 57, a finishing roll 58, and secured at the angle of the arm, as at 56, is one end of a cable 54, which passes upwardly over the pulley 55, mounted on the under face of the bar 5, and has its other end wound on the drum 53. It will thus be seen that upon rotation of the shaft 20, in the forming of the pile, the drum 47 will wind the cable 39 and raise the roll 64 as the size of the pile increases, and at the same time the drum 53 will wind the cable 54 and raise the arm 62. To permit the arm 62 and the box 30 to fall down to normal position, I provide each of the drums 47 and 53 with a clutch, adapted to be released by means of the lever 48, the weight of said arm and box being suflicient, when the clutches of the drums are released, to permit them to drop and unwind the cables from the drums.

The stringers 6 are properly braced by means of'the truss form which comprises the depending bars 59 and the truss member 60.

Below the roll 64and mounted in the couplings by means of the fastening member 71 is the pile winding shaft or arbor 73, having formed thereon the wire retaining hooks 74. Thus when thcbars 10 and 10 are raised by means of the jacks 8 and 8, the shaft 73 will be raised also, thus permitting either end of the shaft to be raised or lowered independently of the other end, the purpose of which will appear in the description and operation of the machine.

Arranged across the sills 1 are the three tracks 7 5 for engagement between the wheels 7 6 which support the carriage 7 O. This carriage comprises the longitudinal beams 7 2 and the transverse beams 71 which support the table 70. Extending transversely of the carriage and through one end of each of the longitudinal bars 72 is a rear shaft a series of reels 75 having the wire A wound thereon. Mount.- ed transverse yet the opposite end of the carriage are the parallel pile supporting rolls and 81 blocks 83 on the carriage adjacent to the rolls 80 and 81 is a wire roller 7 6 over which passes the wires from the drums 75', across the table 70' and have their free ends attached to the hooks 7 4 on the shaft 73. At the'end of the rollers 80 and 81 is a truncated cone shaped roller 65 mounted in the bearing blocks 83.

The reels 7 5 are mounted to turn with the shaft 7 3, and when sufficient wire has been unwound and disposed across the table 7 0 it is necessary to stop the shaft so that the wires when wound on the shaft 7 3 will draw the carriage forward. To do this I provide a brake device of any suitable form, to hold the shaft 73 stationary in its bearing, the form shown in the drawing being; the pin 84 adapted to be passed down through an opening 85 in the end of the shaft, the end of the pin engaging against a stop pin 86 in one of the bars 7 2.

The operation of the machine, for making cylindrical piles, is as follows: The wires A are unwound from the spools 7 5, drawn under the carriage, over the rollers 76, 80, and 81, across the platform 70, to the shaft 78 where their respective ends are secured each to a hook 74. Woven or expanded metal sheets are then laid on top of the wires A and the platform 70. Concrete is then shoveled thereon and smoothed in an even layer. The rollers 64 and 80 and 81 together with the shafts 73 are adjusted in parallel relation by means of the jacks 8 and 8. The machine is then set in operation which, through means of the gears 15, 16, and 19 cause the rotation of ,the shaft 73, and the wires, fabric, and concrete to be rolled thereon. As the shaft 73 rotates, and winds the material thereon, the wires A draw the carriage until the rollers 80 and o 81 are beneath the shaft '7 3, when the wires A may be cut. The material for the pile is now located between the rollers 64 and the rollers 80 and. 81, and also the tapered rollers 65 and 65. The continued rotation of the parts of the machine shape the pile into cylindrical form, with the. exception of the end between the tapered rollers which is given a corresponding taper. At the same time that the materials are being wound on the shaft 73, the drum 47 and 53 wind up the cords 49 and 49 54 and 54 and draw the rollers 58 and 64 up as the. diameter-of the pile increases. The former roll 58 rests against the face of the pile and serves to finish the same, smoothing the surface, and scraping off superfluous concrete. This finishing operation is continued until the concrete has setenough to be easily handled, when the shaft 73 bearings, and withdrawn from the pile, the pile being set away to harden. The machine is then reversed, and the carriage moved back to the original position.

To form a cylindrical pile without the tapered end, the operation is the same,,eX- cept that the rollers 65 and 65 are removed.

When it is desired to make a pile tapered in its entire length, one end of the shaft 7 3 is raised by means of one or the other of the sets of jacks. The roller 64is also similarly adjusted, but at its opposite end, so that the longitudinal space between the roller 64 is tapered. By means ofthe pin and slot connections 22 and 23 the beams 10 may be adjusted to incline the shaft 73 laterally. The movements of the parts are the same as above described with reference to the cylindrical pile, the outer face, of the pile longitudinally thereof being inclined instead of horizontal. The sliding bearings 30 are adapted to be adjusted so that I bination, a supporting standard, a core shaft, a horizontally traveling platform, a pivotally held finishing roller, a vertically reciprocating former roller, means for rotating said core shaft and synchronously moving said platform in a horizontal plane, said finishing roller in an arc and the former roller in a vertical plane.
